For custom painting, I need to use Graphics object.
I am using custom implementation of the INPaintCallback:

stockChart.PaintCallback = new CustomPaintCallback();

public class CustomPaintCallback : INPaintCallback
{
public void OnAfterPaint(NPanel panel, NPanelPaintEventArgs eventArgs)
{
Graphics graphics = eventArgs.Graphics.DeviceGraphics;
/// graphics is null ?????
}
}


With some research, I found that Graphics object is null when NTooltipTool is used together with any chart.
Is there anyway to get this Graphics object together with NTooltipTool?
